Serial terminal for 5xx

In case you need to access the IPLC5xx terminal via the serial port, you must have a TTL 3.3V to RS232 converter, eg Domat M070.

Connection 10pin. connector inside the IPLC, where the IPLC5xx normally has a display (the IPLC5xxB has a free connector), is as follows:

1 - GND
2 - 3.3 V power supply for the converter (do not connect if the converter is powered from an external source)
9 - RXD
10 - TXD

The cable can also be made from a serial cable for some mobile phones.
